Structural steel software specialist AceCad has undertaken the biggest development to its software since it started out in the 1980s. Greg Corke reports on the philosophy behind the new evolution suite.

A Revit family component is a functional element that must communicate the design intent, occupy a realistic space within the building. Paul Woddy looks at how to get the best out of Building Information Modelling software.

In the CAD calendar, December is always Autodesk University (AU) and it is always in Las Vegas. The 2009 event was the 17th consecutive AU and, as in previous years, consisted of non-stop presentation, classes, meetings and socialising.

Moving to Building Information Modelling does not just assist in the co-ordination and production of plans and elevations. With an accurate 3D model, simulation and analysis can lead to better designs.

For decades Computer Aided Design tools concentrated on the 2D documentation phase of the design process. More recently, Google SketchUp has highlighted the demand for 3D conceptual design tools, which has lead to the development of a number of competitive systems.

Revit Structure Extensions is a set of tools only available to Revit Structure subscription holders. These tools range from producing a simple grid via an Excel spreadsheet to reinforced concrete drawings.

Originating from Hungary in 1982, Graphisoft’s ArchiCAD is the most mature 3D Building Information Modelling solution on the market. With a very loyal installed base over Europe and America, the company regularly produces updates and add-ons. Martyn Day evaluates two of the latest enhancements.
